Question about steel? PLZ?

Question

I have a granite table top

4 feet by 6 feet

approxipletly 450-500 pounds

I need a steel base

so my question it:

if i have two 18 guage bases will this hold it?

- Thanks inadvance

Answer 1

I wouldn't want to try it. With something that heavy, I would want a beefier base.

Answer 2

I don't think that you supplied enough information.  Is the 18-gauge steel rolled into tubes representing legs, or is it bent into a four-sided box (x inches tall) with the granite placed on top, or ... ?
